About 10 years ago I did my first Gentoo install on a PPC G3. It was a mainboard from a Blue&White G3 Mac which I built together myself and fitted into a normal PC case later. Then came a IBM Netvista Pentium III, a Netvista P4, a Samsung NC10, Thinkpad T60, T61 and now an Acer laptop. Of course I've checked out other distros but mostly only besides Gentoo which was always my main OS since then.
